How do I install the SIRAX BM1250?
Mount the device in a panel cutout of 92x92 mm, secure with clamping brackets. Connect voltage and current inputs per wiring diagram. Power supply: 90-260 V AC/DC. Refer to the manual for detailed connections.
What is the accuracy of the SIRAX BM1250?
The device offers Class 0.5 for energy measurement and Class 0.2 for power (per IEC 61557-12). It provides true RMS readings for distorted waveforms.
Can I connect the SIRAX BM1250 to a PLC?
Yes, it supports RS485 Modbus RTU and Ethernet TCP/IP for integration with PLCs, SCADA, or building management systems.
How do I reset the energy counters?
Press and hold the SET button for 3 seconds to access the setup menu. Navigate to 'Energy Reset' and confirm. Partial reset for tariff counters also available.
What is the maximum current input?
Direct input up to 6 A. For higher currents, use external current transformers (CT) with secondary 5 A. The device can display scaled values up to 6000 A.
How do I configure the communication parameters?
Enter the setup menu via the front buttons. Set BAUDRATE (c4800 to 115200), PARITY (none/even/odd), STOP BITS, and DEVICE ADDRESS (1-247). Default: 9600, 8, N, 1.
What does the 'ALARM' LED indicate?
The red ALARM LED lights when any measured value exceeds the configured limits. It is associated with relay outputs that can trigger external alarms.
Can I measure harmonics with this device?
Yes, it provides harmonic analysis up to the 31st order for both voltage and current. Data available via Modbus or on the display.
How do I clean the front panel?
Use a soft, dry cloth. Do not use solvents, abrasive cleaners, or water. Ensure the device is powered off when cleaning.
Where can I find the user manual?
The manual is available for free download as a PDF on the official support page or from the retailer. It includes wiring diagrams, Modbus registers, and configuration details.
